Figure 3
Surface electrostatic potential of PaMarR. (a) Overall electrostatic potential. Surface electrostatic distribution is viewed in two different orientations. The scale ranges from −5 kT e⁻¹ (red) to 5 kT e⁻¹ (blue). The black dashed ellipse indicates the DNA-binding site of PaMarR. (b) Surface electrostatic potential at the entrance to the effector-binding site. Palmitic acid is represented as sticks. The black dashed circle denotes the entrance. (c) Electrostatic potential isocontour shown as red (−1 kT e⁻¹) and blue (+1 kT e⁻¹) surfaces. The arrow indicates the DNA-binding site. (d) Electric field generated by the surface electrostatic potential of PaMarR. The surface electrostatic potential distribution is the same as in (a). The arrow indicates the DNA-binding site. The electric field map is contoured and described at the −0.5σ level. (e) Solvent-accessible surface area. The black dashed circle indicates the entrance to the effector-binding site. Blue spheres indicate water molecules.
